Pepper bacterial wilt is a typical bacterial soil-borne disease. Its pathogen is Pseudomonas palustris. Bacteria survive for a long time, mainly through the invasion of plant stems. Farming operations such as transplants and loose soils, as well as root wounds caused by insects and other injuries can all cause bacterial invasion in the soil and breed rapidly under conditions of high temperature and high humidity.
The early symptoms of pepper wilt only showed the wilting one to a few leaves wilting. The initial wilting was still recoverable and later became stable.
Control methods:
1, sowing early. Bacterial wilt usually occurs in mid-to-late June. In order to avoid the peak of the onset of the disease and the outcome of the fruitful period, sowing can be advanced.
2, choose a well-drained sandy loam soil cultivation. After the soil is deeply turned, it is sprayed with 800 times of new high-fat membrane to disinfect the soil and keep it warm, which is beneficial to the germination and growth of the seeds.
3, more than three years of rotation. Bacterial wilt can damage a variety of Solanaceae crops. Where the former is tomato, eggplant, and pepper, it is not appropriate to grow peppers.
4, pay attention to drainage. Ralstonia solanacearum can spread along with the water stream. It should be cultivated with narrow ridges and high ridges. Attention should be paid to timely drainage and no water can accumulate in the ridge.
5, pruning, loose soil, topdressing and other work should be completed before the onset of the disease, after the onset of special attention can not be loose soil weeds, if weeds, can only be removed by hand to avoid injury to the root.
6. The diseased plant was found and removed in time. The general and the neighboring soil were sprayed and sprayed on the tree to sterilize and prevent the spread.
